122930 ÷ 10 
We're looking to find how many times 10 goes into 122930.

Step 1:
When dividing 1 by 10, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 10

On to step 2:
The number 10 fits into 12 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 10 from 12.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 10

Step 3:
22 divided by 10 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 2 after subtracting 20 from 22.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 10

Advancing to step 4:
10 goes into 29 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 122.0
If we take 20 away from 29, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 10

Moving on to step 5:
When dividing 93 by 10, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1229.0
The remainder is 3 after subtracting 90 from 93.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 10

Step 6:
10 goes into 30 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 12293.0
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12293.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12293.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12293.0, with a leftover of 0.0.
